用稻草栽培金针菇,成本低,效益好,特别是南方盛产水稻,原料来源广,可就地取材。我们经过两年的栽培实践,摸索出一套稻草栽培金针菇的高产技术,生物效率在95％以上,现将该技术介绍如下。 (一)栽培季节 金针菇属低温型菌类,子实体形成需要较低的温度。我所位于罗甸县城郊,该县素有贵州“天然温室”之称,年均温19.6℃,1月份平均气温10℃。根据当地气候条件,每年11月中旬至1月下旬为制栽培袋的适期,12月下旬至3月上中旬为出菇期。 (二)菌种选用及制备 经试验,罗甸地区以杂交19金针菇(引白天津市农科院情报所)为好,产量高,出菇整齐。用综合培养基(小麦、阔叫木屑各100g,土豆200g,蔗糖、琼脂各20g,磷酸二氢钾2g,硫酸镁1.5g,VB_1、四环素各1片,水1000ml,pH自然)制备母种,菌丝满管后即制备原种或直接制备栽培种。原种、栽培种的培养料配方:玉米粒97％,石膏、过磷酸钙、蔗糖各1％。先将玉米粒浸泡24小时,然后煮至九成
Flammulina with straw cultivation, low cost, good efficiency, especially the rich rice in the south, a wide range of sources of raw materials, available locally. After two years of cultivation practice, we explored a set of high-yielding techniques of straw cultivation Flammulina velutipes with a biological efficiency of more than 95%. Now we introduce the technology as follows. (A) cultivation season Flammulina is a low-temperature fungi, fruiting bodies need to form a lower temperature. Located in the outskirts of Luodian County, the county is known as Guizhou’s “Natural Greenhouse,” with an average annual temperature of 19.6 ℃ and an average temperature of 10 ℃ in January. According to the local climatic conditions, mid-November to late January each year for the cultivation of bags suitable period, late December to mid March for the fruiting period. (B) selection and preparation of strains tested, Luodian area to 19 hybrid flammulina (cited Tianjin Academy of Agricultural Sciences intelligence) as well, high yield, fruiting and tidy. The mother species was prepared by using a total culture medium (100 g each of wheat, broadleaf, 200 g of potatoes, 20 g of sucrose, agar, 2 g of potassium dihydrogenphosphate, 1.5 g of magnesium sulfate, VB1, each of tetracycline and 1000 ml of water, After the mycelium is full, it can be used to prepare the original species or directly prepare the cultivated species. Original species, cultivar cultivation materials Recipe: 97% of corn, gypsum, superphosphate, sucrose 1%. Soak the corn kernels for 24 hours and cook until 90%
